A panel system includes a tab panel having at least one tab extending therefrom. The tab panel has a core and a facesheet adjacent the core. The panel system includes a slot panel having at least one slot receiving the corresponding tab of the tab panel therein. The slot panel has a core and a facesheet adjacent the core. The panel system includes a clip positioned between the tab panel and the slot panel. The clip is at least partially received in the slot. The clip has a tab panel securing member being secured to the tab panel and the clip has a slot panel securing member being secured to the slot panel. The clip securely joins the tab panel to the slot panel.

A connection element is provided for connecting at least two components. The connection element has at least two spherical, sphere-shaped or sphere-type or sphere-like sections, wherein a first section of the at least two sections is provided for the connection with a first component, and the second section of the at least two sections is provided for the connection with a second component.

Injection molded parts with a small dimension that exhibit high heat resistance are described. Thermoplastic compositions that can be utilized to form the injection molded parts are described. The thermoplastic composition includes a polyarylene sulfide and a crosslinked impact modifier. The thermoplastic composition can also include siloxane polymers, thermoplastic elastomers, or other additives that can further improve the characteristics of the injection molded parts.

Apparatuses include first and second monolithic members that are coupled together, that are configured to move relative to each other, and that are configured so that they cannot be decoupled from each other without destruction of one or both of the two monolithic members. Apparatuses further include a third monolithic member configured to be selectively coupled to at least one of the first monolithic member and the second monolithic member. Methods of forming and using such apparatuses also are disclosed. Some monolithic members are formed utilizing an additive manufacturing process so that they are restricted from being decoupled from each other. Some apparatuses define clamps. Some clamps are used to precisely align laser projection alignment targets for use with laser projection alignment systems.

A solar power system can include a rail and a solar module disposed on the rail. A clamp assembly can couple the solar module to the rail. The clamp assembly can have a clamped configuration in which the solar module is secured to the rail and an unclamped configuration. The clamp assembly can comprise an upper clamp member, a lower clamp member coupled to the rail, and a stabilization member mechanically engaging the upper clamp member and the lower clamp member. The stabilization member can prevent rotation of the lower clamp member relative to the rail when the clamp assembly is in the clamped and unclamped configurations. In the unclamped configuration, the stabilization member can be biased such that the upper clamp member is disposed at a sufficient clearance above the rail to permit the insertion of the solar module between the upper clamp member and the rail.

A clip for assembling corners of hollow members such as the rails and stiles of an extruded aluminum door. The clip has an L shape and may feature a double L shape. A portion inserts into the hollow of a first member and is attached thereto. Another portion extends into the other hollow member for attachment thereto to form a sturdy joint without welding. Pairs of clips may be used at each corner.
